Abstract (en)

A hand operated circular saw comprising; a base plate (26) comprising a channel (24) arranged to cooperate with a guide rail member, a motor housing, a gripping portion and a switch for manual operation of a motor disposed in the motor housing, and a cowl coupled to the base plate and arranged to accommodate at least a portion of a saw blade disposed on an output spindle coupled to the motor, said output spindle being moveable with respect to the base plate and/or cowl between a first position and a second position thereby providing a plunge-cut action of the circular saw; the base plate further comprises: a mechanism arranged to cooperate with a portion of a guide rail such that, when the circular saw is disposed on a guide rail, the mechanism offers relatively low friction between the saw and guide rail in a first direction thereby allowing the saw to be moved manually with respect to the guide rail in the first direction, and the mechanism offers relatively high friction between the saw and guide rail in a second direction thereby preventing free movement of the saw with respect to the guide rail in the second direction, wherein the mechanism comprises one or more cams (60,62) urged into a first position by a spring.
